Understanding the geography of the United States begins with knowing America’s 50 states, their capitals and their flags. This knowledge helps provide context for news, travel and history, and builds a strong foundation for understanding regional differences. This app offers a structured learning system designed for long-term retention rather than short-term quiz repetition. At the core is an adaptive spaced repetition system that adjusts review intervals based on your actual memory performance. If you remember an item after a longer interval than expected, the next interval increases. If you hesitate or make a mistake, the interval decreases without resetting your progress. This ensures that your study time focuses exactly on what still needs reinforcement. Two learning modes support different learning preferences. Multiple Choice offers quick practice and is ideal for early recognition training. Self-Assessment strengthens active recall: you try to remember the answer before rating whether you knew it, almost knew it or did not know it. This approach is highly effective for long-term memory. The app includes all 50 U.S. states in a single clear category. You can choose between several question directions, such as State → Capital, Capital → State, State → Flag and Flag → State. You may adjust the configuration at any time without losing progress. Each category has its own test in which all items appear once. Based on your performance, you earn a silver or gold medal, giving you a clear overview of your progress. A full card browser is included for browsing states, capitals and flags independently of learning sessions.
